Abstract

An inertial mass device is realized with at least two inertial masses which can rotate relative to one another, one of which is connected to a hub disc which is effectively connected to elastic elements of a damping device and preferably with its radially inner area forms a hub for the location of a bearing arrangement. Corresponding to the hub disc there is at least one planet wheel of a planetary gear train which acts between the inertial masses. The hub disc, on its side facing away from the planet wheel, on a specified radius around its axis of rotation, has indentations formed in the peripheral direction at specified intervals, each of which indentations forms a projection toward the planet wheel on the opposite side of the hub disc, whereby the projections form a toothing on the hub disc, by means of which the hub disc is engaged with the toothing of the planet wheel for the transmission of a torque between the inertial masses.
